The invention relates to the use of a structural adhesive film for bonding and sealing a hem flange connection between panels. The structural adhesive film comprises at least one adhesive layer and at least one layer with a porous structure. The adhesive layer comprise an epoxy compound as well as an epoxy curing agent.

Multilayer structural adhesive film

The disclosed retroreflective sheet contains a retroreflective layer and a polyurethane surface protecting layer, wherein the surface protecting layer contains at least a reaction product of a polyol with either a polyester backbone or a polycarbonate backbone and a trifunctional or higher aliphatic isocyanate, and the glass transition temperature Tg of the surface protecting layer is 50&#xb0; C. or higher, and the tan &#x3b4; of the loss tangent at 120&#xb0; C. is 0.1 or less.

Retroreflective sheet, license plate, and manufacturing method thereof

An ultraviolet cross-linkable pressure sensitive adhesive sheet includes a (meth)acrylic copolymer of a monomer containing a (meth)acrylic acid ester having an ultraviolet cross-linkable site. The storage modulus of the pressure sensitive adhesive sheet before ultraviolet cross-linking is from 5.0&#xd7;10to 1.0&#xd7;10Pa at 30&#xb0; C. and 1 Hz and 5.0&#xd7;10Pa or less at 80&#xb0; C. and 1 Hz. The storage modulus of the pressure sensitive adhesive sheet after ultraviolet cross-linking is 1.0&#xd7;10Pa or more at 130&#xb0; C. and 1 Hz.
